# Created by Robert Osfield.
#In ffmpeg code, old version use "#include <header.h>" and newer use "#include <libname/header.h>"
#In OSG ffmpeg plugin, we use "#include <header.h>" for compatibility with old version of ffmpeg
#We have to search the path which contain the header.h (usefull for old version)
#and search the path which contain the libname/header.h (usefull for new version)
#Then we need to include ${FFMPEG_libname_INCLUDE_DIRS} (in old version case, use by ffmpeg header and osg plugin code)
# (in new version case, use by ffmpeg header)
#and ${FFMPEG_libname_INCLUDE_DIRS/libname} (in new version case, use by osg plugin code)
# Macro to find header and lib directories
# example: FFMPEG_FIND(AVFORMAT avformat avformat.h)
MACRO(FFMPEG_FIND varname shortname headername)
# First try to find header directly in include directory
# old version of ffmpeg put header in $prefix/include/[ffmpeg]
# so try to find header in include directory
